You know it was a good night when only 3 out of 152 pics are facebookable

when someone's name is common enough to look up on facebook easily and find them.

Michelle Johnson vs. Michelle Jawnsun. Michelle Jawnsun would be a name that you could put in facebookand find the person easily that you are looking for because their spelling is a bit odd. Michelle Johnson is too common to be facebookable because too many people share that name it is harder to find that person.

Due to the upsurge in high school facebookers whose only other friends are other high school facebookers, facebookable is defined as any picture that displays the said facebooker's status as a crazy partier or otherwise macho person. Thus, the only non-facebookable pictures are ones that show people with their grandmothers, or helping out orphans.

"Shit man, don't put that picture up, that's not facebookable!"
"Why not? It's of you reading to your brother before he goes to sleep."
"Exactly. Here, take this one, it's me passed out in a pool of my own vomit after a killer party!"
"Whoa brah you are so cool!"
"Check out the cigarette in my hair!"
